Introduction
CD59 is a cell surface glycoprotein which regulates complement-mediated cell lysis, and it is involved in lymphocyte signal transduction. CD59 is an effective inhibitor of the complement membrane attack complex, whereby it binds complement C8 and/or C9 during the compilation of this complex, thus inhibiting the incorporation of multiple copies of C9 into the complex, which is essential for osmolytic pore formation. In addition, CD59 has a role in signal transduction pathways in the activation of T cells. CD59 gene mutations cause CD59 deficiency, a disease resulting in hemolytic anemia and thrombosis, and which causes cerebral infarction.
Description
CD59 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 100 amino acids (26-102) and having a molecular mass of 11.3kDa.
CD59 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
The CD59 solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 1mM DTT and 10% glycerol.
Stability
